Mayday is the international radiotelephony distress signal. It signifies an imminent danger requiring immediate assistance, so the station in distress requests urgent help from anyone who can respond. In practice, a Mayday call is spoken three times at the start to grab attention and indicate a true emergency, followed by the vessel or aircraft’s identity, position, the nature of the emergency, and any critical details like the number of people on board. This signal prioritizes the distressed station in all traffic and prompts responders to act quickly. It’s not a routine check-in, it doesn’t simply tell others to switch to an emergency channel, and it isn’t a request to repeat a transmission—its purpose is to declare a life-threatening situation and secure help.
